To all whom, it mag concern Be it known that (I, FERDINAND SCHAUB, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of-New Jersey, have invented certain new and useful Improvements in Crossover- Insulators for Electrical Conductors, of which the following is a full, clear, and exact specification.

This 'inventionrelates to cross-over insulators for electrical conductors.

The present improvement is especially adapted for use inthat specie of device wherein electrical wires crossing one another will be securely clamped between the respective members ofthe insulator and so held apart.

The present application is a division of my application Serial No. 442,648, filed July 9, 1908, for insulators. In the application above referred to there is illustrated a twopart electrical insulator wherein the wireseat comprises recesses formed in the meeting faces of the two members. In the showing of such application the wire is clamped in a wire-seat formed in a special manner therein referred to between two members of an insulator. Such special formation of wireseat may be employed in connection with an insulator for a single wire or in connection with an insulator for separating a pair of crossed wires. The present improvement is a part of a general insulating scheme set forth in part in such parent application.

In one form of the present improvement the base member and cap member will remain substantially as shown-in the parent application and the crossover member will be inserted. between these. Or the cap for the base portion may be provided with a formed that the .wlre will reeve freely' wire-seat constituting a cross-over, which seat may be complete in the cap, or it may be completed by a cap similar to that employed upon the base for a one-wire insulator. When the cap carries a cross-over Wire-seat complete in itself, this may be so through the seat. If, however, the wire is to be clamped in the cross-over seat, a twopart construction for the seat is preferable.

For commercial reasons it will probably be found .desirable to-permit the two-part insulator to remain intact, or the parts may be paired when the crossover feature a dded'. It also will be convenient, in installing wires, to employ the cap'to hold. the wire going in one direction, and then when it is desired to add the cross-over, this element will be added to the structure without thenecessity of throwing away some part of one wire relativeto the other and of the variousparts of the device is immaterial so far as the formation of the insulator itself is concerned. Fig. 2 is a central longitudinal section of the device illustrated in F 1. Fig. 3 is a' top planview of the crossover illustrated in Figs. 1 and 2. Fig. 4 is a top plan view of the base illustrated in Fig. 2. Fig. 5 is a view of the cap member illustrated in Fig. 2, and is either the top or bottom of the same, since this cap member is shown reversible. Fig. 6 is a top plan view of the assembled insulator of Figs. 1 and 2, shown on a reduced scale and with the wire-seat of the cross-over disposed transversely to the wire-seat of the base portion. Fig. 7 is an elevation of another form of my invention, wherein the cross-over wire-seat is made complete in the capmember. Fig. 8 illustrates the insulator shown in Fig. 7, with a portion of it shown in central longitudinal section. Fig. 9 is a plan view, either top or bottom, of the crossover cap illustrated in Figs. 7 and 8; and

Fig. 10 is an illustration of a two-part cap' and this portion of the device, for conven-- ience, will be referred to as the base. The base l1, h er.ein illustrated,-is shown provided in its upper face, or the face which wardly-curved projection 15, which will direct a kink in the wire into the recess of the other'member of the insulator. WVhen the members are assembled in the manner illustrated in Fig. 2, the wire in the recess 12 will be directed upwardly into the annular recess 16, formed in one face of the cross-over member, which recess will be surrounded by an annular flange 17. The

flange 13 will be located inv position to register with some portion of the flange 17, and the recess'12 to register with some portion of the recess 16, in whatever relative angular position of adjustment the two members may be. This will provide for one of the wires. The other of the-wires will be disposed in the wire-seat 18, of the crossover member 19, which wire-seat will be provided with an upwardly-curved projection 20, and a' flange 21, which flange 21 ,will register with a flange 22, of the cap-member 23, and the recess 18 will register with an annular recess 24, in the cap member, irrespective of the relative angular positions of adjustment of the parts. In the present showing both sides of the cap member are provided with the recesses 24 andflanges 22, so that this part is reversible, which will save time in applying the device. I

The cap member is interchangeable with the crossover member, so that the cap memher and base member may be used for constituting a one-wire insulator. When it is desired to cross a wire over the wire which is seated in the insulator, the cross-over member will be added, the bottom face of which corresponds with the bottom face of the cap member, and the upper face of the cross-over member corresponds with the upper face of the base member, so that the.

cross-over member will constitute the cap for the base member and will itself constitute the base upon which the cap will then be seated. Some suitable fastening device, as for instance a screw 25, will pass through the assembled members and into'the surface upon which the insulator is to be mounted for clamping the parts together upon the wires.

' To afford greater protection against'the contacting of the wires which arecrossed, one of the wire-seats may be provided with shields for the wire carried th reby, which shields will be interposed between the two wire-seats. In the present instance a crossover member is shown provided with a pair of outwardly directed shields 26, which form a continuation of the wire-seat 18. By this means the crossed wires are securely Outwardly of the recess there is 10-- prevented from coming into engagement one with the other. -When the parts are assembled and the fastening device applied, the projections 15 and 20 will kink the wires and so prevent longitudinal, movewith the cap member. In Figs. 7, 8, and 9 the same form of wire kinking and clamping wire-seat is illustrated in the bodgy and cap members. The cap member is hown provided with a wire-seat in the form of a tube 27, through. which the wire may be 35 permitted to reeve as occasion, may demand. Or the tubemay be of such a diameter that the wire will not readily move therethrough. The cap member illustrated in Fig. 10 is in many respects similar .to the cap mel'nher illustrated in Figs. 7, 8, and 9, this, however, being separated on a plane of cleavage indicated by the dotted line 28.

The cap member in this figure comprises a two-member part, the two members being 9 identical one with the other and reversible and interchangeable. Each is shown comprising half. a tube 29, which is carried by the cap 30. One side of the cap has a recess 31, for receiving the pin 32, carried by the other member. This tube may be of suflicient internal diameter relative to the diameter of thewire to permit the wire to move longitudinally through the tube, or

the wire may be clamped between the two halves, as for instance, they may be of sufficient diameter toclamp the wire upon the" application of power to the fastening device.
